Abstract
Fifty-nine leprosy patients (31 tuberculoid, 28 lepromatous) were HLA typed and compared to 125 healthy individuals who had no known contact with leprosy patients in the past. HLA antigens were determined by a microdroplet lymphocyte toxicity method. To detect 31 HLA antigens, a total of 58 antisera were used in a no. T-7 reasearch tray. AW24 antigen showed the greatest deviation. The frequency of this antigen in leprosy patients was 25.4% and that in normal subjects of the control group was 63.2%. The difference in frequency between the 2 groups was statistically significant when the P value was corrected for the number of antigens being tested. Uncorrected P values of the BW39, A9 and B8 antigens were also statistically significant. Frequencies of the majority of HLA antigens in tuberculoid leprosy patients were similar to those of corresponding HLA antigens in lepromatous leprosy patients.
